Title: Plug-in power recorders and battery mics?
Post by: dwissl on May 25, 2006, 09:08:58 AM

I recently ordered a Sound Professionals preamped mic. The manual says, that its input socket provides 9V plug-in power and that one should only connect microphones to it, which need plug-in power.
Is this consumber type plug-in power as dangerous to batterey powered mics, the AT822 for instance,  as 48V phantom power? Or can I use dynamic mics and battery powered condensor mics with plug-in power devices like the SP preamps or MD recorders without having to create a special plug-in power disabling cable?

Thanks

Devices with true 30-48 volt phantom power have ON-OFF switch for running mics not requiring, or that may be damaged from this type powering.  Make sure to turn Phantom Power off when not needed.

Lower voltage 1.5-9.0 volt 'mic power' input devices will not harm mics not requiring any type of plug-in-powering feature.
